Swap USDT from Polygon to ETH on Ethereum

Swap USDT from Polygon to ETH on Ethereum. Tether USDT leaves Polygon. Native ETH is what can arrive on Ethereum. A stable balance becomes the gas coin on chain id 1.

Sell 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Buy the native label 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, which means ETH on Ethereum and not WETH. WETH remains 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 if you needed the wrapper. Polygonscan shows Tether leaving. Etherscan shows ETH. Read how cross-chain bridges work if the gas label looks like a token contract.

The label is not a contract to approve

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE has no token bytecode. On chain id 1 it means ETH you can spend on gas. If the wallet asks you to approve that string, you are off this route. Etherscan should show a native credit.

WETH is the wrong finish

Contracts that demand 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 will not accept native ETH until you wrap it. Wrapping needs a little extra ETH for gas. If you wanted the wrapper delivered directly, this page is the wrong quote.

Tether on Polygon is not Tether on Ethereum

0xc2132D05D31c914a87C6611C10748AEb04B58e8F is the Polygon contract. Ethereum Tether is 0xdAC17F958D2ee523a2206206994597C13D831ec7, and this route does not buy it. You are leaving Tether entirely and taking ETH price exposure.

Keep POL for chain 137

The source fee is POL, with blocks around 2 seconds. That timing is not the bridge. Ethereum's own blocks are around 12 seconds. Leave POL so the approval of USDT and the swap can both land.

Frequently asked questions

What is the best way to swap USDT from Polygon to ETH on Ethereum?

Sell 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Buy the native label 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, which means ETH on Ethereum and not WETH.

Does 0xEeee mean ETH on Polygon too?

On Polygon the same label means POL, the gas coin of chain id 137. On Ethereum it means ETH. This route sells Tether, not POL, and it buys Ethereum ETH. Polygonscan will not show the ETH credit. Etherscan will not show the Polygon USDT debit. Polygonscan will not show the ETH credit.

Will I receive WETH if the pool prefers it?

Not from this quote. The output is native ETH. WETH is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2, a separate route. ETH is not WETH. If you sign here, plan on a native balance you can later wrap yourself, which takes more ETH for gas. This quote will not deliver the wrapper.

What if the quote shows a weak minimum?

Do not sign it. USDT against ETH can move before the wallet opens. Request a new quote and read the new floor. No finish time is given for the bridge. About 12 seconds is only Ethereum's block, visible later on Etherscan. Refresh the quote if the floor looks wrong.
